Integrate Rewards for Earn Products
Vault depositors on Morpho can earn rewards beyond base lending yield. Integrating rewards display and claiming is essential for providing competitive APY and maximizing user returns.
What's Unique for Earn Products
When building earn products, understand that vault depositors earn rewards from two sources:
- Direct Vault Campaigns: Rewards distributed directly to vault depositors
- Forwarded Market Campaigns: Rewards from underlying markets where the vault allocates liquidity
Net APY = Vault Native APY + Vault Campaign Rewards APR + Forwarded Market Rewards APRIntegration Steps
Follow the centralized rewards tutorials with vault-specific considerations:
Step 1: Fetch Vault Rewards Data
Follow: Fetch Rewards Data
Vault-specific notes:- Query both
state.rewardsandstate.allocation[].market.state.rewards - Calculate weighted average for market rewards based on allocation
- Use
supplyAssetsUsdto determine weights - Alternatively, use
netApyconvenience field for simple total APY
Step 2: Display Rewards in Your UI
Follow: Integrate Rewards Display
Vault-specific notes:- Prominently display Net APY (native + all rewards)
- Show breakdown: base yield vs. rewards
- List reward tokens with their respective APRs
- Optionally show which markets contribute to forwarded rewards
Step 3: Enable Reward Claiming
Follow: Claim Rewards
Important: The claiming process is identical for all Morpho users (vault depositors, borrowers, market suppliers). Both Merkl and URD use the same claiming flow regardless of how rewards were earned.
